13 Claims.

This invention relates to a combined article of furniture and radioreceiving set.

More particularly, this invention contemplates an improved floor lamphaving various instrumentalities of a radio receiver distributed inseveral parts of the lamp in such a unique manner that the dimensions orproportions of standard fioor lamp designs need not be materiallyaltered v to accommodate the receiver and the presence of the latter isnot readily apparent upon viewing the lamp.

Another advantageous feature of this inve tion resides in the provisionof a combined floor lamp and radio receiving set wherein the severalparts of the radio receiver, including the variable condensers, aregrouped together to form a chassis unit assembly in the pedestal of thelam-p substantially midway between the base and shade of the lamp.

Another object of this invention resides in the provision of a combinedfloor lamp and radio re ceivingset wherein the pedestal of the lampconstruction is formed of two sections and wherein the chassis unitassembly of the radio receiving set is interposed between adjacent endsof the sections.

Still another advantageous feature of this invention consists in theprovision of a construction of the type set forth in the precedingparagraph wherein the chassis unit of the radio receiving apparatus isdetachably secured to the upper end of the lower section of the pedestaland wherein the upper section of the pedestal is removably secured tothe chassis unit.

Still another object of this invention resides in mounting a loudspeaker unit in either or both the base section of the lamp or in theintermediate section containing the chassis unit and also consists inmounting a tuning control element for the variable condensers on thechassis unit independently of the upper section of the pedestal. As aresult, the upper section of the pedestal may be removed withoutinterfering with the performance of the radio receiving set.

A still further object of this invention consists in the provision of aradio receiving chassis unit assembly embodying a combined volumecontrol rheostat and on-off switch in addition to the variablecondensers previously mentioned.

Still another feature of this invention resides in rotatably supportinga pair of tuning dial members on the chassis unit beneath the lower endof the upper section of the pedestal for rotation independently of eachother about the axis of the pedestal and respectively operativelyconnected to the variable condensers and rheostat for actuating thelatter.

A still further advantageous feature of the present invention resides inthe provision of a construction wherein the loud speaker of the radioreceiving set is embodied in the intermediate section of the lampconstructionin compact relationship to the chassis unit and wherein thepower transformer, rectifier, and amplifier tubes are housed in the baseof the lamp construction.

In addition to the foregoing, the present invention contemplates acombined lamp and radio receiving set wherein the upper section of thepedestal forms a support for a shade unit embodying a loud speakerassembly which may be an addition to the loud speaker assemblypreviously mentioned.

With the foregoing, as well as other objects in view, the inventionresides in the novel construction of the parts which not only lendthemselves to economical manufacture but, in'addition, permits the sametobe readily assembled or disassembled 'for servicing. This constructionwill be made more apparent as this description proceeds, especially whenconsidered in connection with the accompanying drawings, wherein:

Figure 8 is a fragmentary sectional View illustrating a slightlymodified form of construction; I

Figure 9 is a wiringdiagram of the embodiment shown in Figure 3.

Referring now more'in detail to the drawings,

it W111 be noted that I' have-illustrated in Figure 1 a combined lampand radio receiving set comprising a base section I9, a shade sectionII, and an intermediate section I2 supported substantially midwaybetween the shade and base sections. In addition, the lamp constructionis provided with a pedestal I3 comprising a pair of aligned sections I4and I5 in the form of tubes. The intermediate section I2 is supported onthe upper end of the bottom section I4 of the pedestal and the lower endof the latter is removably secured to the base It of the lamp. The shadesection II of the lamp is secured to the upper end of the top section I5of the pedestal and the lower end of this section is detachably secureden the intermediate section I2 of the lamp.

The base I!) of the lamp is provided with a bottom wall It in the formof a disc having an opening I! through the center thereof and having theperiphery detachably secured to an annular appearance ring It by meansof the screws I9. The appearance ring I8 is removably secured to aspider 23 positioned in the base It] at'the upper end of the latter.Upon reference to Figure 5, it will be noted that the arms 2| of thespider extend radially outwardly to a point adjacent the side walls ofthe base and are secured to the appearance ring I8 by means of spacers22.

The parts within the base It are concealed by a cover 23 having thelower end seated against an annular shoulder formed on the appearancering I8 and having the upper end bearing on the top of the spider 20.The upper wall of the cover 23 is formed with an enlarged openingthrough the center thereof for receiving a ring 24 which, in turn, issecured to the spider by means of the fastener elements 25. Theperiphery of the ring 24 is threaded for receiving a nut 26 which servesto clamp the cover against the spider 29.

In the specific embodiment of the invention illustrated herein, theparts of the wiring diagram enclosed by th line 2'! in Figure 6 arelocated in the base I0 and are secured in any suitable manner to thebottom wall It of the base. Among the parts secured to the bottom wallI6 are the powertransformer 28, amplifier tube 23, rectifier tube 30,filter condensers 3i, and A. F. output transformer 32. These parts areelectrically connected to a socket 33 having a detachable plug 34 which,in turn, is electrically connected to the radio receiving parts inanother section of the lamp; The arrangement is such that theinstrumentalities of the radio receiving set in the base may be removedas a unit with the bottom wall I6 of the base upon disengaging the plug34 from the socket 33.

The lower end of the bottom section M of the pedestal is secured to afixture 35 which, in turn, is secured to the top of the ring 24 by meansof the fastener elements 25. The upper end of the section I 4 isfashioned to form a seat for engagement with the lower end of theintermediate section I2 of the lamp and is removably secured to thelatter by means of a tie bolt 31. The tie bolt 31 extends upwardlythrough a central opening formed in the spider and projects through thetube forming the lower section I4 'of the pedestal. The tie bolt isprovided with a head 38 at the lower end having a slot therein adaptedto be engaged with a screw driver or other suitabl implement insertablethrough the opening I! in the bottom wall of the base.

The intermediate section I2 of the lamp comprises a casing 39 having abottom wall 46 provided with a depending reduced annular hub portion 4!adapted to have a seating engagement with the upper end of th lowersection I4 of the pedestal. The top of the casing 39 is provided with aremovable top wall 42 in the form of a disc having the periphery seatedupon an annular shoulder 43 extending inwardly from the side Wall 44 ofthe casing and having a relatively large opening 45 through the centerthereof. Secured to the portion of the top wall 42 surrounding theopening 45 is a ring 46 having threads on the periphery thereof fordetachably securing a disc 41 in seating relationship with the top wall42 of the casing. The disc 41 forms a table top and is serviceable tosupport articles of different nature on the lamp.

The top wall 42 of th casing 39 is removably held in place by means of aspider 48 having a hub portion 49 extending into the hub portion 4| ofthe casing and threadedly engaged by the upper end of the tie bolt 31.In addition, the spider is provided with radially outwardly extendingarms at having vertically upwardly projecting extensions 5| adjacent theside walls of the casing and detachably secured to th top wall 42 bymeans of the fastener elements 52. The construction is such that the tiebolt 31 cooperates with the spider 48 to secure the casing 39 andremovable top Wall of the latter to the upper end of the bottom sectionI4 of the pedestal.

Suspended from the top wall 42 of the casing 39 is a plate 53 havinggenerally radially extending vertical partitions 54 projecting upwardlyfrom the top surface thereof and provided with lugs 55 at the outer endswhich are removably secured to the underside of the top wall 42 by meansof the fastener elements 56. Secured to the central portion of the plate53 is a casting 51 having a tubular portion 58 extending upwardlythrough the ring 45 with its axis concentric with the extended axis ofthe pedestal sections.

According to the present invention, the various parts of the radioreceiving circuit surrounded by the line 59 in the diagram shown inFigure 6 are carried by the plate 53 and form a chassis unit assembly.Among the parts carried by the plate 53 are three variable condensers 60having the usual stator plates GI and the rotor plates 62. The shafts63, upon which therotor plates of the condensers are respectivelysecured, extend vertically and are spaced from each other in concentricrelationship to the axis of the tube 58. Each shaft 63 has a pinion 64secured to the upper end thereof and these pinions mesh with a centraldriving gear 65 mounted on the casting 51 for rotation about the axis ofthe tubular portion 58 of the casting.

The gear 65 is rotated from a position above the table top 41 by meansof a tuning dial 66 secured to the upper end of a bushing 61 which, inturn, is rotatably sleeved on the tubular portion 58 of the casting. Thelower end of the bushing 6'! is secured to a gear 69 which, in turn,meshes with a pinion III rotatably mounted on a vertical stub shaft IIsuitably supported on the casting 51. A pinion I2 of relatively smalldiameter is also rotatably mounted on the shaft ll beneath the pinion I0and meshes with one of the condenser gears 64 which also meshes with thecenter gear 35. Inasmuch as the remaining condenser gears 64 also meshwith the center gear 65, it follows that the condenser gears 64 aresimultaneously adjusted upon rotation of the dial 66. From theforegoing, it will be seen that the gearing between the dial 66 and therotors of" the condensers is of the speed reducing type so that thecondenser rotors may be accurately tuned from the dial.

In addition, a combined volume control rheostat and off-on switch 14 areamong the parts of the radio receiving set carried by the plate 53. Uponreference to Figure 2, it will be noted that the rheostat 14 is providedwith a downwardly extending shaft 15 operatively connected to the lowerend of a vertical shaft 16 through the medium of gearing 11. The shaft16 is journalled in the casting 51 and is provided with a pinion 18 atthe upper end thereof adapted to mesh with an internal gear 19 securedto a second dial control disc 88. The control disc 80 is positioneddirectly above the dial 66 and is supported for independent rotationabout the axis of the tubular portion 58 of the casting.

In Figure 2 of the drawings,-I have illustrated a speaker unit 8! asalso supported in the casing 39. The speaker cone 82 faces upwardly andis detachably secured to the underside of the plate 53 by means of thefastener elements 83. The hub portion 84 of the speaker extends into thehub portion 49 of the spider 48. When installing the speaker in theposition mentioned aforesaid, the bottom wall 40 and the side wall 44 ofthe casing are perforated, as at 85, to permit the passage of sound.

It follows from the above that the chassis unit of the radio receivingset and the speaker form a compact assembly capable of being removed asa unit. Attention is called to the fact at this time that those parts ofthe radio receiving set in the casing 39 to be connected to the parts inthe base are electrically connected to a plug 86 located in the upperend of the bottom section I4 of the pedestal. The plug 86, of course,detachably engages a socket 81 which is electrically connected to theproper parts in the base I!) of the lamp. With the above construction,it will be noted that disengagement of the tie bolt 31 from the hub 49of the spider 48 permits the casing 39 and chassis unit, including thespeaker 8|, to be removed as an assembly.

The upper section l5 of the pedestal I3 has a ring 89 secured to thelower end thereof by means of the fastener elements 98. The lower end ofthe ring is counterbored and threaded for connection with the upper endof the tubular portion 58 on the casting 51. The arrangement is suchthat the section I5, together with the lamp shade assembly supportedthereby, may be readily removed from the intermediate section l2, ifdesired. Removal of the section l5 of the pedestal and the associatedlamp shade assembly H does not interfere with the operation of the radioreceiving apparatus, previously described, and, therefore, theconstruction may be converted from a lamp to a simple radio table orstand. In the event the section I5 of the pedestal is dispensed with, itwill, of course, be advantageous to provide a finishing member on theupper end of the tube 58. Such a member is shown in Figure 7 by thereference character 9!.

As shown in Figures 3 and 9, the upper end of the pedestal isthreadedfor engagement with a tubular fixture 93 which, in turn, supports thelamp shade 94 and the usual illuminating means 95. In the presentinstance, the tubular fixture 93 also supports a speaker assembly 96.This assembly includes a power transformer 91, a rectifier tube 98, anamplifier tube 99,-and a speaker cone I98. These elements areelectrically conthe tube 58 and adapted to 'detachably engage acooperating socket I02 which, in turn, is electrically connected to therequired radio receiving parts in the chassis unit assembly, previouslydescribed as supported in the casing 39. The manner. in' which thisconnection may be accomplished is shown by the dotted lines in Figures 6nected to a plug l0l located in the upper end of and 9. It will, ofcourse, be understood that the speaker assembly 96 in the shade unit mayeither be used in addition to the speaker assembly 9| in the casing 39or may be substituted for the latter speaker. In the event it issubstituted for the speaker assembly 8|, the power unit in the base mayalso be eliminated.

In Figure 8 of the drawings, I have shown a slight. modification whereinthe top wall 42 of the casing 39 is removably secured to the annularshoulder ,43' at circumferentially spaced points by means'of fastenerelements I85. The construction is such as to permit the chassis unitassembly, including the speaker, to be detached from the casing byremoving the top wall 42'. It will, of course, be understood that thecover disc 41 must be removed before access can be obtained to thefastener elements I85. This cover disc is threadedly mounted on the ring4% so as to permit the same to be readily removed when desired. It mayalso be pointed out that in this embodiment of the invention, the spider48 may be entirely eliminated, if desired. In the event the'spider 48 iseliminated, theupper end of the tie bolt 31' may be secured directly tothe lower end of the'hub portion 4| of the casing 39.

In the event the embodiment shown in Figure 8 is used, it is desirableto provide a second detachable plug connection between the parts of theradio circuit in the base and the parts of the radio circuit in thechassis unit. A detachable plug for this purpose is shown in Figure 8 ashaving a socket. 81' electrically connected to the plug 86 in the upperend of the pedestal section I 4 and as having a plug 86 electricallyconnected to the parts of the radio receiving circuit in the chassisunit. The detachable plug 86' and socket 81' are located in such aposition in the casing 39 to be readily accessible upon 1 removing thetop wall 42' of the casing.

Thus, from the foregoing, it will be observed that I have provided anovel construction of combined article of furniture and radio receivingapparatus. It will also be noted that the construction shown is such asto permit its optional use as a radio table or as a floor lamp. Ineither case, the parts of the radio receiving set are compactlydistributed in the several sections of the article of furniture to notonly afford efficient operation of the radio circuit, but to alsoprovide for obtaining a design having a neat and pleasing, appearance.In addition, it will be observed that the construction is such as topermit readily assembling and removing the parts of the radio receivingset.
